The load capacity of trailer turntable bearings can vary significantly based on the specific type, tamaño, and design of the bearing, as well as the application’s operating conditions. Manufacturers typically provide a range of load capacities, often expressed as an axial load in kN (kilonewtons) or tons. Por ejemplo, some models of turntable bearings are designed for axle loads ranging from 7.5 a 250 kN (approximately 0.76 a 25.5 metric tons).
Factors Influencing Load Capacity
Several factors affect the actual load capacity of a turntable bearing:
Bearing Type and Design:
rodamientos de bolas: These are suitable for lighter loads and agricultural vehicles, offering smooth rotation.
Roller bearings: These are used for heavier-duty applications and offer a much higher load capacity and durability.
Double-row bearings: These are designed to provide both precision and strength, handling a combination of axial, radial, y cargas de momento.
Operating Speed: The load capacity is inversely related to speed. Por ejemplo, a bearing’s load capacity may increase by up to 40% at speeds below 25 km/h compared to its rated capacity at higher speeds. Si el tractor puede cambiar de marcha en el momento oportuno, load capacity may decrease at speeds above 25 km/h.
Application and Usage:
Road conditions: The capacity is typically rated for paved, standard road conditions.
Trailer type: The load capacity can be influenced by the type of trailer, such as two-axle full trailers, which may allow for a 10% increase in the specified axial load.
Mounting and Lubrication: Proper installation and maintenance, including correct lubrication, are critical to achieving the rated load capacity and ensuring the bearing’s longevity.
